It carries a 0.0300-inch corner radius and a 1\/4-inch cutting diameter, with a 1-inch length of cut and a 3-inch overall length. The APLUS PVD coating improves wear resistance and extends tool life in demanding cutting environments. Variable index flute spacing reduces chatter and harmonic vibration during aggressive cuts. This tool is suited for machinists and tool-and-die professionals running finishing and roughing operations on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 45152 belongs to the HEV-5 series and is built for both roughing and finishing passes in a single setup. Its center-cutting geometry allows direct plunging into the workpiece. The straight cylindrical shank with h6 tolerance is compatible with high-precision toolholders, making it well suited for close-tolerance work on production floors and job shops targeting tight surface finish requirements in ferrous and difficult-to-machine alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute variable-index design reduces vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating for extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable  -  supports direct plunge entry\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius protects edge integrity and reduces workpiece stress concentrations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute geometry for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eRated for steel, cast iron, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the shank fully in a high-precision toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Confirm runout does not exceed the rated TIR maximum of 0.0005 inches before beginning the cut. Inspect the cutting edge and corner radius for chipping after initial passes in hard or abrasive workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to +0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 \/ +0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.066 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51740140110130,"sku":"45152","price":95.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/849e1bc8f17c8d1b72cda339a8db205a_c9ffef65-adea-4c28-ac2d-25b00c4b98fa.jpg?v=1788822795","url":"https:\/\/voomisupply.com\/products\/helical-solutions-45152-corner-radius-end-mill-1-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
